Phraseological competence is one of the main challenges for language learners. Phraseodidactics, as one of the applied fields of Phraseology, fosters this competence by providing teachers and students with certain tools and techniques. In this collective volume, eight specialists put forward the relevance of this field and formulate guidelines for a good acquisition of phraseological units in German as a foreign language. They confront theoretical and practical principles that lie at the foundation of idioms teaching, and contribute to consolidating Phraseodidactics as a significant scientific branch in this field.
